We hence conducted a "real-life" application approach simulating the 66 inactivation of dried surface residing infectious SARS-CoV-2 by a mobile handheld UV-C 67 emitting device and an UV-C box designed to decontaminate medium-size objects. Simulating the situation that exhaled droplets or aerosols from infected 115 individuals contaminate surfaces, we produced a high-titer SARS-CoV-2 infectious stock and 116 dried 35µL of this stock corresponding to ~4*10^6 IU/ml in each well of a 6-well plate. Of note, even short UV-C treatment of the dried virus in the context of the moving "fast" 135 regimen completely inactivated SARS-CoV-2, as no infected cells were detected based on 136 fluorescence protein expression (Fig. 1b) . Altogether, our data 143 demonstrate that UV-C regimens that expose high-titer SARS-CoV-2 to doses down to 16 144 mJ/cm² are sufficient to achieve complete inactivation of the virus.	./cache/cord-302160-4yfvspaq.txt	./txt/cord-302160-4yfvspaq.txt
